Opposite for me. I use Chromium on Desktop and Firefox on mobile. Firefox Focus for everyday's browsing, and Firefox Mobile for long term sessions (I have 200 opened tabs of hacker new on Firefox Mobile, it's ridiculous)
Plus, Adblock extensions on Firefox Mobile work great.
But with the ad-blocker installed, you get a bonus speed boost that doesn't apply to the other browsers...
That's why I use Brave on mobile.
I like Bromite on Android.
try Firefox Quantum in the phone. it's super slick and I've really been digging it.
the workflow is the for everyone but because it supports 1pass filling the constant clear doesn't feel that bad
